The solution to bolt overload problems!


The majority of bolts are tightened and hence are preloaded. This preloading tends to reduce the loading acting on the bolt but does not eliminate it. When external loads are applied to the joint, the bolt will sustain a proportion of that load. If the load is sufficiently high the bolt can be overloaded and subsquently fail. The BOLTCALC program determines the load being sustained by the bolt and checks if the resulting stress will exceed the bolt's minimum yield strength.

Determination of the load increase acting on the bolt
The program will determine the load increase the bolt sustains when an external load is applied. The stiffness of the bolt and joint is considered in the analysis as well as the location of the load introduction level within the joint.
